Title: Method and device for cutting cables, tubes, and the like
IPC: B21F99/00
Filed: 1950-03-28
Abstract: 678,181. Severing cables and tubes. DUCH, G. V. A., and DUCH, M. A. March 28, 1950 [March 29, 1949; March 7, 1950], No. 7718/50. Class 83 (iv). A method of electrically cutting cables and tubes comprises gripping the cable or tube on both sides of the cutting zone with encompassing jaws, causing an electric current to flow through the jaws so that the metal of the cable or tube melts at said zone, slightly bringing the jaws together while the metal melts to bunch the molten metal and moving the jaws apart to cut the cable or tube. The jaw 1 comprises a base element 2 and a removable cover 3 pivoted at 4. An eccentrically mounted clamping lever is pivoted at 6 on the base 2 and has an arcuate notch 7 for receiving a transverse stud 8 on the cover 3. Semi-cylindrical bushings 9 and 10 are accommodated in the jaws for clamping the cable, the upper bushing being secured by a screw-threaded rod 13 and knurled nut 14 to the cover 3, the lever bushing being located in the base element 2 by means of a stud 17. The bushings and their recesses in the jaws may be of polygonal shape. The jaws are displaceable along the axis 21-22. After cutting a cable according to this method a sprue head of molten metal is formed on the free ends of the cable which welds together the strands of the cable to which may be welded a hook, ring, slip or clasp. The cable ends may be machined, e.g. screw-threaded. A refractory sleeve 29 having an internal recess may cover the cutting zone so that on the inward movement of the jaws the molten metal is dammed and beads are formed on each end of the severed cable. Two sleeves 31, 32 spaced apart on each side of the cutting zone may be used to form the beads. The sleeve 29 may be in halves which are held around the cable by a clamp 36.

Filed: 1931-03-14
Abstract: 367,591. Optical sound-reproducing apparatus. PATHE CINEMA, ANCIENS ETABLISSEMENTS PATHE FR—RES, 6, Rue Francoeur, Paris. March 14, 1931, No. 7939. Convention date, March 31, 1930. [Class 40 (ii).] In the reproduction of sound by a light beam directed through a photographic record on to a light-sensitive cell, provision is made for compensating automatically in the output circuit for fluctuations in the light source whether energized by an electric current or pressure gas. As shown, light from a source 1 is directed by a prism 12 and lens 6 through a photographic sound record 3 on to a lightsensitive cell 5 connected through an amplifier 8 to a speaker 9, and compensation for fluctuations in the source 1 is effected by connecting a light-sensitive resistance 10 in a shunt circuit from the cell 5 and subjecting this resistance to a beam from the source 1 directed through a prism 13. If desired the resistance 10 may be influenced from a separate source of light energized from the same electric or gas supply as the source 1, and an adjustable screen 11 of graduated opacity may be inserted in the path of the beam to the resistance 10 and adjusted to produce a minimum damping effect, subject to satisfactory compensation, on the output circuit of the cell 5.

Convention date, March 11, 1929. [Class 64 (ii).] A thermoelectric device controls the effect of one or more fluid jets on a pressure-sensitive device which controls, with or without a relay, a heating device. A thermoelectric pyrometer f is connected to the moving coil c of a measuring instrument, and the axis g of the coil carries a disc h mounted eccentrically. Compressed air is delivered through a pipe m and jets i, k which are arranged opposite to other jets n, o on the other side of the disc h. Rotation of the eccentric disc h varies the pressure difference in the pipes p, q due to the partial obstruction of the jet i or k and the diaphragm u is correspondingly deflected. Oil or other fluid under pressure is delivered by the pivoted jet t against the two jets x, x<1> to an extent determined by the deflection of the jet t, and the piston y of a servomotor z, controls in any suitable manner a valve in a fuel supply pipe or an electric resistance. In alternatives, one, or more than two, compressed air jets may be employed, or the eccentric disc may be replaced by the segment of a cylinder.

Patent GB-594983-A (GB)
Title: Improvements relating to aromatic hydrocarbons
IPC: C07C7/00
Filed: 1945-04-04
Abstract: Pure aromatic hydrocarbons are prepared from mixtures containing them, together with indene and non-aromatic hydrocarbons, such as petroleum and coal tar naphthas, by contacting with 65-85 per cent sulphuric acid, separating the hydrocarbon layer, producing an aromatic concentrate therefrom, and recovering the pure aromatic hydrocarbons by controlled sulphonation and hydrolysis of the sulphonic acids.  The acid to hydrocarbon ratio is generally between 1 : 1 and 1 : 10 by volume. Feedstocks consisting of aromatic fractions or aromatic extracts obtained by solvent extraction, and generally boiling at about 160-185 DEG  C., are treated batchwise or continuously with about 80 per cent acid, and the hydrocarbon layer steam distilled to remove polymer material.  If desired, a solvent extraction may be effected to separate aromatics.  Preferably, however, the hydrocarbons are treated with 96 per cent sulphuric acid to sulphonate the aromatics, the acid layer then being diluted, heated to about 90 DEG  C. and steam distilled.  Hydrocarbons distil over at about 140-185 DEG  C.  Fractionation yields crude mesitylene, pseudocumene, and hemimellitene fractions from which the pure hydrocarbons are recovered by controlled sulphonation and hydrolysis, alone or combined with fractional distillation and crystallization. In an example, the indene fraction from coal tar naphtha, B.R. 170-180 DEG  C., is treated with an equal volume of 80 per cent acid for 30 mins., and the separated hydrocarbon layer again treated similarly.  Sulphonation followed by hydrolysis and fractionation yields, inter alia, hemimellitene-containing fractions from which the pure hydrocarbon is recovered by controlled sulphonation and hydrolysis.

Abstract: 1298638 Magnetic cores SPANG INDUSTRIES Inc 20 Feb 1970 8309/70 Heading H1H Magnetic molybdenum-containing permalloy particles (e.g. 2% Mo, 81% Ni, balance Fe) are blended with a non-agglomerating material (0À02-0À05% by wt. of magnetic particles), annealed in a non-oxidizing atmosphere and electrically insulated, the insulation (dry weight) comprising not more than 0À4% by wt. of the magnetic particles, and containing a plasticizer non-decomposable at the temperature required for applying the insulation. A non-agglomerating material is defined as one that remains inert or non-reactive at powder annealing temperatures, e.g. talc or kaolin. The particle sizes of the magnetic particles may be such that about 1, about 3 and about 6 parts by wt. have average sizes of 90, 65 and not greater than 37 microns respectively. The annealing temperature may be about 1250‹ F. The particles may be insulated by applying one or more coats (with intermediate drying) from a slurry of a metal silicate and an aqueous suspension of a metal oxide. The first coat may comprise sodium silicate and milk of magnesia; subsequent coats may also contain kaolin. The plasticizer, e.g. ammonium lignosulphonate may be added as a final coating to the insulated particles, or applied as an intermediate coating during this insulation. Starch, sugars or glycerine together with wetting agent are suitable for intermediate coating. The insulated particles may be compacted at more than 100 tons/in<SP>2</SP> to form cores, which are then annealed in a non-oxidizing atmosphere, e.g. H 2 . The cores may then be surface etched and oxidized by heating in a free O 2 -containing atmosphere, e.g. at 850‹ F. for 15 mins. The resulting cores have high permeability coupled with low loss.
